Dongliao County fire, 24 October 2026 东辽县 · Dongliao County, Xifeng County
Dying down · last detection 4 Nov 2026, 17:13 UTC
The fire started on 24 October 2026 in Dongliao County, China, and satellites saw it burning for 12 days. Copernicus’s global GWIS system rebuilt a burnt perimeter of 3,219 hectares from heat detections, spread across 2 municipalities.
Number 218 in China in 2026, of 1095.
GWIS near-real-time perimeter, from the layer that changed in October 2025: this fire is not compared with fires from earlier years, because since then the GWIS layer gives more and larger perimeters.
The power measured by the satellite is low (8.6 MW in the strongest hotspot), more typical of grass or stubble burning, or a slow surface fire, than of a large crown fire.

Is it still active?
No detections since 4 Nov 2026, 17:13 UTC. That usually means no flame is visible from space any more, although hotspots may remain. Satellites pass a few times a day and cloud or smoke can hide the fire: a lack of detections is not an official extinction. Each country’s emergency service declares a fire contained or out.

This area had burned before
22% of the perimeter overlaps earlier fires recorded since 2016: 4 ha in 2023, 87 ha in 2024, 719 ha in 2025. Part of it burned more than once, so the yearly figures add up to more than the 724 ha that had burned before.

People and buildings inside the perimeter

Residents≈ 7,100
Inside the perimeter there were about 60 hectares of built-up land and about 7,100 residents (GHSL 2025, satellite-based estimate).
This is an estimate on 100 m cells, made from satellite imagery and census data: it does not mean that homes burned or that anyone was harmed. The perimeter also contains land that never burned. The GHSL 2025 epoch is a projection made from 2020 and earlier data.

Frequently asked questions
- How long did the Dongliao County fire last?
- According to the heat detections seen by satellite inside the perimeter, it burned from 24 October 2026 to 4 November 2026 (12 days). The perimeter dates it from 28 October 2026 to 4 November 2026.
- How much area did it burn?
- The perimeter GWIS (Copernicus) rebuilt from heat detections is 3,219 hectares (32.2 km²). It is an estimate: official national figures may differ.
- Which municipalities burned?
- The fire entered 2 municipalities: Dongliao County (3,104 ha, 1.3 %); Xifeng County (113 ha, 0.0 %).
- Is the Dongliao County fire still active?
- No fire detections since 4 Nov 2026, 17:13 UTC. A lack of detections is not an official extinction.
- What was the weather like?
- During the fire the temperature reached 13.8 °C, humidity dropped to 18 % and gusts hit 67 km/h. The fire danger index (FWI) reached 30, class High.
- Where does this data come from?
- From the GWIS (Copernicus) burnt perimeter, NASA FIRMS VIIRS hotspots and the administrative boundaries of China (geoBoundaries). It is not an official report.
Where to verify it
A satellite detection is not an official report. Final figures and the fire’s status are published by each country’s emergency service.

Does something look wrong on this page?
This page is built from satellite data and official records, and it sometimes gets things wrong: the wrong dates, the wrong town, two fires merged into one, or something that was not a wildfire at all. If you know this fire first-hand (you live nearby, saw it, fought it or reported on it), tell us what really happened and we will check it.
Report an error
How we know this
- Perimeter: GWIS (Copernicus), rebuilt from heat detections rather than mapped on imagery.
- Dates adjusted with the VIIRS detections inside the perimeter, which said 28 October 2026 to 4 November 2026. 84 Suomi-NPP VIIRS detections on those dates.
- We have not matched this page with any official record.
- Weather: ECMWF IFS model, provisional until the ERA5 reanalysis arrives.
- Built-up area and population come from the JRC Global Human Settlement Layer (epoch 2025, 100 m cells), summed inside the perimeter: an estimate of what was there, not a damage count.
Where this data comes from
The perimeter comes from the Copernicus Global Wildfire Information System (GWIS), which rebuilds it from MODIS and VIIRS heat detections and publishes it under CC BY 4.0. It is not measured on imagery as in Europe, so it is an estimate. Heat detections come from the VIIRS sensors aboard Suomi-NPP and NOAA-20, distributed by NASA FIRMS at 375 m resolution. Municipal boundaries come from geoBoundaries ADM3 (Open Data Commons Open Database License 1.0). The area per municipality is computed by WorldFires by crossing the perimeter with those boundaries, so it may differ from each country’s official figure.
